ABRADING DEVICE.

Be it known that 1, CHARLES S. GUsTAF- soN, a subject of the King of Sweden, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Abrading Devices, of which the following is a specification.

This invention relates and it has more particular reference to means for holding a strip or sheet of sandpaper, emery-paper or the like whereby it can be effectively manipulated for smoothing or cleaning rough or dirty surfaces, the main object being to provide a simple, cheap, compact and useful device for the purposes specified.

With the foregoing object in View my invention consists essentially of a rectangular hand-block having one end slightly beveled and transversely slotted to receive one end of a sheet of abrading material adapted to be folded over said block, and a clamping bail journaled in said block for gripping engagement over the aforesaid beveled end and underlying abrading sheet of material.

In the further disclosure of my invention reference is to be had to the accompanying sheet of explanatory drawings constituting a part of this specification and in which like characters of reference designate the same parts in both the views.

Figure 1 is a perspective view of my improved abrading device ready for use and as adapted for smoothing wood surfaces with a strip of sand-paper; and,

Figure 2 is a central longitudinal section through the same.

According to the embodiment ofmy invention illustrated, I makeor cut a rectangular handblock 10 of appropriate material, such as wood thereby providing opposed parallel fiat faces 11, 12 and ends 13, 1 1 the former 13 of which is at right angles to both faces 11, 12 whereas the latter 1% is beveled or inclined with. relation thereto. Trans versely of the beveledend 14 I cut or form-a saw-cut or groove 15 of appropriate depth to snugly receive the inner end 16 of a strip or length of sand-paper 17 which is folded around the hand-block 10 with its free end 18 overlying the folded-in inner end 16 as Specification of Letters Patent.

shown. To look or firmly retain the folded over length of sand-paper 17 I preferably employ a wire or rod bail-like clamp having a central loop or finger piece 19 and bent to provide gripping portions 20, the ends being then turned at right angles towards each other to constitute pivotal portions 21, which latter are journaled in opposed holes 22 provided for their reception in the sides 23 of the hand-block. It will thus be clearly seen that the gripping portions 20 firmly clamp the folded-over ends 16, 18 together on the beveled end 14: whereby a very simple and effective means is provided for securely holding the sand-paper 17 on the handblock.

From the foregoing description and an examination of the drawings the advantages and manner of using my improved abrading device will be self-evident to those acquainted with the arts wherein it is employed, therefore, further statement in that connection is deemed unnecessary with the exception that I do not limit myself to the precise details of shape and pattern.

Having'described my invention, what I claim as new and desire to secure by Letters Patent is:

1. A device for holding a sheet of abrading material consisting of a rectangular block providing spaced parallel faces, an end at right angles thereto and an opposed transversely grooved end inclined with respect to both parallel faces, and a bail pivoted in the sides of said block by inturned ends, said bail having a manipulating finger and spaced portions adapted to clamp on the aforesaid inclined end.

2. A sand-paper holder consisting of a rectangular block of wood providing spaced parallel faces, an end at right angles thereto and an opposed transversely grooved end beveled with respect to both said parallel faces, and a bail pivoted in the said block CHARLES s. GUSTAFSON.
